Academic career and research
Royer has made several contributions in the geosciences, including using leaf size and shape to reconstruct paleoclimates, using the stomatal distributions of plants to reconstruct ancient levels of atmospheric carbon dioxide, and doing extensive work on the correlation between atmospheric CO₂ and temperature over geologic timescales. He has been a Geological Society of America Fellow since 2011.{{cite web|url=http://droyer.web.wesleyan.edu/research.htm|title=Dana Royer|work=wesleyan.edu}}
He co-authored a paper in 2008[http://droyer.web.wesleyan.edu/Target_CO2_(Hansen_et_al).pdf Paper by Hansen et. al.]droyer.web.wesleyan.edu {{Webarchive|url=https://web.archive.org/web/20170506082719/http://droyer.web.wesleyan.edu/Target_CO2_(Hansen_et_al).pdf |date=2017-05-06 }} with climate scientist James Hansen and others that suggested humanity aim for 350 parts per million CO₂ in the atmosphere to avoid climate change that could threaten human civilization. This has been widely cited and was reported on by several media outlets.{{cite web|url=https://thinkprogress.org/hansen-et-al-must-read-get-back-to-350-ppm-or-risk-an-ice-free-planet-2b9a29cab989#.qylb3psq5|title=Hansen (et al) must read: Get back to 350 ppm or risk an ice-free planet|date=18 March 2008|work=thinkprogress.org}}
